3, 6 & 15-W medical DC/DC converters offer low leakage current

XP Power today announced the JHL & JHM series of encapsulated, isolated and regulated DC-DC converters for medical applications. Available with single and dual outputs, the 3 Watt JHL03, the 6 Watt JHL06 and the 15 Watt JHM15, are all packaged in industry-standard format cases. Their size is model dependant, ranging from an industry standard DIP-24 for the JHL03 and JHL06 through to 1.6 x 1.0 x 0.4 inches for the JHM15 series.

All models are approved to the 3rd edition international medical safety standards EN60601-1:2006 and ANSI/AAMI ES60601-1:2005, feature a low 2uA maximum patient leakage current, and offer 2 x means of patient protection (2 x MOPP). They also have a double / reinforced isolation barrier that provides 4000 VAC maximum input to output isolation for one minute with a 250 VAC working voltage.

The JHL03 and JHL06 series single output models are available with 5, 12 or 15 VDC and duals +/- 12 or +/- 15 VDC. Two input range variants are available across the JHL series, 10 – 17 or 20 – 30 VDC, accommodating nominal 12 or 24 VDC applications. The JHM15 series comprises two 2:1 input voltage range options of 9 – 18 or 18 – 36 VDC. Singles provide 5, 12, or 15 VDC and duals +/- 5, +/- 12 or +/- 15 VDC models.

An output voltage trim function is available across the single output models of JHL/JHM series, and provides a +/- 10% adjustment of the output in order to accommodate losses or for special applications.

The units meet the EN55011 Level A EMI standard for both conducted and radiated emissions without the need for any external filtering components.

Capable of operating in most environments and over an extended operating temperature from -40 to +80 degrees, the JHM15 can deliver the full output power up to + 60 degrees C without derating. The JHL03/06 series operate from -20 to + 80 degrees C with full output power available up to +50 degrees C.

Typical applications include medical devices that require a low power isolated and regulated DC-DC converter that has an extremely low patient leakage current and reinforced insulation.

The JCL03 single output series is priced at $25.77 for 500 pcs orders and is available from Newark, Digi-Key, or direct from XP Power and come with a 3 year warranty.
